In case there are other users who might be interested in equipping
their desktop PC with eSATA capability, as Tim mentions there are
devices that can easily be installed on the computer case's I/O back
panel that can provide this capability - direct SATA-to-SATA
connectivity.
One such device we've worked with is the SATAPOWPLAT1 device
(see http://www.provantage.com/scripts/cart.dll/x/0/rtspecs/STRT0HA
which Provantage sells for about $11 incl. shipping)
As previously indicated, this device is simply attached to the I/O
bracket on the computer case's backplane. It comes with two external
connectors - the SATA data connector and the 15-pin SATA power
connector. Internally (the other side of its slot plate) is, of
course, the
SATA data connector for a connection to one of the motherboard's
SATA connectors and the normal 4-pin Molex power plug. So it's a
simple matter to connect the device to one of the power leads of your
PS to power the "external" SATA HD.
Note that the SATA data connector on this SATAPOWPLAT1 device
is a standard SATA data connector; it is not an eSATA connector.

On the other hand, here is a backplane expansion strip that
has an External SATA (eSATA) connector:

With respect to the first device you listed, note that it contains *only*
an eSATA data connector unlike the POWERPLAT1 device I
mentioned that contains *both* the eSATA data connector and a
power connector as well. Now that's fine if the user employs an
enclosure with an auxiliary power supply provided to the SATA HD,
but it's a bit more flexible to have this sort of device with a power
connector that facilitates using the computer's internal PS as a
source of power. And the additional cost of the POWERPLAT1
device is negligible.

I think the links that we both gave were for SATA taken to the
exterior,
as opposed to External SATA (i.e. eSATA) Here is the link you gave:
http://www.provantage.com/scripts/cart.dll/x/0/rtspecs/STRT0HA .
Nowhere does the summary mention External SATA or eSATA.
This product's description, though, does mention "eSATA":
http://www.firewire-1394.com/internal-sata-single-esata-bracket.htm ,
as does this:
http://www.firewire-1394.com/internal-sata-esata-bracket.htm .
And yes, both don't include a power connector. It implies that
power must be provided by the external enclosure. Since the
eSATA standard allows for cables up to 2 meters long, though,
NOT running power over cables that long might be a good thing,
especially if several hard drives are involved.

Yes, you are correct in that the POWERPLAT1 device I mentioned contains a
"normal" SATA data connector and not an eSATA connector. Like all these
similar devices, as you know, it still can be used effectively as the
"bridge" to an external SATA HD and facilitate a direct SATA-to-SATA
connection between the SATA HD and the computer. Presumably there is an
advantage to an eSATA connector in that it's a more secure connection and
(according to specifications) a shielded data cable is to be used for the
connection.
Based on our experience to date with this device and similar ones, we really
haven't encountered any signal-type problems that we could attribute to
using a standard SATA data cable as opposed to using a shielded SATA data
cable with eSATA connectors. It's very possible I suppose that if the
computer and related equipment was located in some kind of unusual
environment where various types of equipment generated conflicting signals
of one type or another, the shielded cable together with its eSATA
connector(s) might prevent signal problems in this area. But as I've
indicated we've not run into this situation.
The advantage of the POWERPLAT1 device is, in our view, as I previously
mentioned, i.e., it contains a power connector. We find this addition useful
although it may be of little or no importance to others. Since there's no
additional cost of any consequence with this device as compared with similar
devices not so equipped, we simply prefer it.
I might mention that all the SATA data cables we've been using to date (both
standard & eSATA) have not been longer than 1 meter.
